Comment= # 7 on bug 79338<= /a> from Jos=C3=A9 Su=C3=A1rez 
Hmmm... the problem actually seems to not be related to llvm.

I managed to obtain a crash dmesg log (see attachment above) while using ll=
vm
3.5 svn 209067 which in theory was a good llvm svn revision. That made me
rethink the cause of the problem and now I think the problem is coming from=
 the
kernel.

So I tried linux 3.14 (3.14.0-031400-generic #201403310035), which I had us=
ed
before the 3.15 rc's started to come out. The thing is that with llvm 3.5 s=
vn
209708 and linux 3.14 the gpu does not lock up. This svn 209708 llvm revisi=
on
was making the gpu hang quite fast with linux 3.15-rc6 when launching a gam=
e.

GPU hang with 3.15-rc6 with llvm revs higher than 209067 was quite frequent=
, so
could this be that those higher revs are hitting a bug in linux 3.15-rc6?
